  • the toilet bowl 130 is filled with 2 ⁇ 3 L of water to prevent the offensive odor from coming out of the outlet orifice 120.
  • the discharge tube 210 connects the outlet orifice 120 of the toilet main body 100 and the other end connects to a drainage tube 220 running under the toilet main body 100.
  • the discharge tube 210 is made of a flexible material and is curved so that its center of gravity can be shifted vertically upon the application of an external force.

  • the weight 500 is lighter than the weight of the discharge tube 210 plus water introduced in the discharge tube 120 but is heavier than the empty discharge tube 210 alone.
  • a spring can be used as an alternative to the pulley-based moving means in triggering the vertical shift of the discharge tube's 210 gravity center.
  • one end of the spring is connected to the clasp 300 installed at the center of the discharge tube 210, and the other end is attached to the toilet main body 100.
  • the spring should be connected to the clasp 300 in such a way that one end of the spring connected to the clasp 300 is placed at a point higher than the default water level (2 ⁇ 3 L) of the toilet bowl 130 when the spring is contracted.
  • the elastic force of the spring need to be able to withhold the weight of the empty discharge tube 210, but not the weight of the tube 210 filled with water.
  • a latch 710 is placed on the spindle 610.
  • the latch 710 is hooked to a projection of the clasp 300 so that the discharge tube 210 is kept at a fixed position when its center of gravity is raised at or above the default water level (2 ⁇ 3 L) of the toilet bowl 130, resulting in the difference in weight between the weight 600 and the discharge tube 210.
  • a supporting rod 720 is installed to the latch 710.
  • the supporting rod 720 is connected to the flush switching button 1000 to ensure that the release of the discharge tube 210 from the latch 710 is coordinated with the opening of the flush switching valve 900.
  • the latch 710 rotates to release the discharge tube 210 from the latch 710, and then the center of gravity of the discharge tube 210 is positioned below the outlet orifice 120 of the toilet main body 100.
  • water and waste materials in the bowl tank 130 are discharge by passing through the discharge tube 210 and the drainage tube 220.
  • flush water enters the toilet main body 100 through the flush valve 900.
  • the first 0.3 ⁇ 1 L portion of water is used to rinse the toilet bowl 100 and the outlet orifice 120 of the toilet main body before exiting into the discharge tube 210.
  • the discharge tube 210 Since the amount of the water exiting the toilet main body 100 is less than that of coming into the toilet main body 100, the discharge tube 210 is being unfilled, and the tube 210 becomes lighter than the weight 500 pulling the tube 210 through the pulley wire 400 attached to the clasp 300. The center of gravity of the discharge tube 210 moves upward and finally reaches the latch. Then the discharge tube 210 is locked in secure position with the latch 710. This allows water to fill in the toilet bowl 130. When the water level in the bowl tank 130 rises back to the default level (2 - 3 L), the flush switching valve 900 closes up again. INDUSTRIAL APPLICABILITY
  • the water-saving toilet according to the present invention significantly reduces the amount of the water needed to flush a toilet, as compared with the conventional toilets. This was essentially achieved by a dynamic positioning of the waste discharge tube controlled by the balance between the weight of the discharge tube and an externally implemented weight. It also provides a much quieter operation due to the elimination of a siphon-based trap in the toilet bowl.

Abstract

L'invention concerne des toilettes permettant de réaliser des économies d'eau, qui comprennent : un corps principal pourvu d'un orifice d'entrée destiné à l'arrivée d'eau par un tube d'alimentation en eau disposé à l'extérieur du corps principal ; une cuvette destinée à renfermer les excréments extérieurs et l'eau fournie par l'orifice d'entrée ; un orifice de sortie destiné à l'évacuation des excréments et de l'eau présents dans la cuvette ; un conduit d'évacuation dont une extrémité est connectée à l'orifice de sortie du corps principal et dont l'autre extrémité est connectée à une sortie extérieure destinée à servir de passage d'évacuation pour les excréments et l'eau, ledit conduit comportant une partie courbe mobile vers le haut et vers le bas ; et des moyens permettant de déplacer la partie courbe du conduit d'évacuation vers le haut et vers le bas. Selon la présente invention, les excréments peuvent être évacués de la cuvette avec une quantité minimum d'eau du fait de la mobilité du conduit d'évacuation. En outre, la chasse d'eau fonctionne de façon silencieuse puisque son actionnement ne repose pas sur une opération d'ouverture/fermeture caractéristique du principe du siphon.
